Asp.net 4.0 Health Monitor Service question

I am looking at adding the Health Monitoring service to my application.  I know I set up all the settings in the web.config and use it throught my web.config transforms (dev, stg, prod).  My question is this: Once an error happens, it will save the information in the database and send out an email, if you have it set up that way.  Is there a way to highjack the call in your code where you don't want it to go to the error page and still save it to the same database etc?  Basically I want to show my own error on the specific page, but I still want to keep all my errors in the same table and in the same format.
